IMPROVEMENT IN COVERS FOR COOKlNG-STOVES.

Specification forming part of Letters Patent No. 12,968, dated May 31, 1864.

have invented or made new and useful Improvementsin GoversforBoiler-Holes of Stoves and Ranges; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being hereby had to the accompanying drawings, and to the lettersof reference marked thereon, making a part of this specification.

Like letters represent and refer to like or corresponding parts.

Figure 1 is a top or upper surface view thereof. Fig. 2 is a cross-section perpendicular through the center of the said cover. Fig. 3 is the lower or under surface thereof.

The nature of our said improvements and invention consists in constructing a cover for the boiler-holes of stoves and ranges with numerous small apertures for the better protection and durability of the said cover, and through which apertures the atmospheric air above the stove may be admitted to the firechamber or chamber of combustion below, whereby the smoke, gases, or products of combustion arising from the burning fuel therein may be more effectually consumed, and which said apertures may be surrounded by a down ward projecting tube, all of which. are more fully described and set forth hereinafter.

To enable others skilled in the art to which our invention relates to make and use the same, we will now proceed to describe the construction and operation of the same, which is as follows, to wit:

The said boiler-hole cover is made of castiron or other suitable material, and of any size desired for actual use. The thickness thereof may be of the usual or other thickness. A is the cover. B is the recess for lifting the same from the stove or range when used by means of any device constructed for that purpose. D is a flange at or near the outersurface of the cover, which is for the purpose of giving additional strength to the same, as well as to guide it when put into and over the boiler-hole where the same belongs.

G O, &c., are downward projections, and may be made solid, through which holes of a conical or tapering form are drilled or cast, as seen at G C, &c., Fig.2 or they may be made in the form of tubes communicating with the fire-chamber, as and for the purpose aforesaid. The lower end of these holes may be of any size deemed best. The said downward projections may be in any number, size, or length desired, and may contain one or more perforations. We usually put one of the said downward projections in the center of the said cover with one small aperture therein for the aforesaid purpose, around which we place two or more circular rows of said downward projections, and between the same and the flange D, as shown at Fig. 3. It is evident that there may be more of such circular rows, or that the said downward projections, having tubes or apertures in and through the same as aforesaid, may be distributed over the surface of the cover, if deemed best so to do, in any irregular form or shape. The apertures may be drilled directly through the said cover independent of the said downward projections if deemed ady'isable so to do. The cover would not, however, be as strong nor would it be as durable unless made much thicker and with more weight of material than generally used in covers for boiler-holes for stoves. The said apertures may be drilled through the said cover on any angle desired, or at right angles with the upper surface of the said cover, and may be of the same diameter at the top as at the bottom; but we prefer to make them conical or of a tapering form, for then the atmospheric air would enter therein and pass to the combustion-chamber below with much more freedom. Their direction downward will of course be such as to bring the atmospheric air to thoroughly mix and commingle with smoke, gases, or products of combustion arising from the burning fuel below, whereby the gases, &c., become ignited at the temperature of ignition by reason of the introduction of the atmospheric air in the manner aforesaid. The draft of the stove will cause the air above the stove to enter the combustion-chamber through the aforesaid apertures, which will be in quantity sufficient to cause the gas, smoke, &c., to burn as aforesaid. There is great economy in the use of fuel by the use of the said perforated cover. The said cover thus made and used will be much more durable than otherwise made. The combustion and consumption of the gases and smoke will be much more perfect and highly satisfactory.

Having thus described our improvements, In testimony whereof we have, on this 19th what we claim, and desire to secure by Letters day of November 1863, hereto set our hands. Patentis- The employment of the stove or ran ge boilerhole cover A, constructed with downward pro- J jection O, and with apertures in combination therewith, in the manner substantially as and forthe pnrposesherein described and setforth.
